I though the limit was 200 pages before locking. Oh well
I'm 19 years old, recommend me something good!
It depends on what you like and what books you have read before and enjoyed so far. I'll give you some recommendations by genre:
Detective/Mystery/CrimeThe Adventures of Sherlock Holmes, by Sir Arthur Conan Doyle. It's a wonderful collection of short stories, each one with a strange case that Sherlock solves in a really smart way that makes it seem obvious. Although it was written in the 19th century, it's an easy read and you'll find Watson reaction's to Sherlock methods quite funny.
The Mystery of the Yellow Room, by Gaston Leroux. This was actually the only book that I really enjoyed back in high school. The story is about a murder of a woman, but the weird thing is that she is locked on a room, so when her parents enter the place, they find her bleeding, but there are no sings of the killer or how he entered the room. The plot twists are mind-blowing.
FantasyHarry Potter, by J.K Rowling. Ok, not the most creative suggestion, but who cares? I read the entire series a few years ago, in a few months and I wasn't even a child and enjoyed it. This series have made a lots of kids realize they enjoy reading, and even some adults. Although the movies are great, they miss a lot of details and scenes, but the most important thing: Harry's sarcasm. I still don't get how such an important part of his personality wasn't showed on the movies, but anyways, this is a really good series. Books 5 and 6 might drag a bit, since they're really long, but it's still an easy read, no matter the age.
I could recommend you another books, but unfortunately, those are either too long for a nobel reader or the writer really likes lots of unnecessary details. So, I wouldn't recommend you the Lord of Rings trilogy, as Tolkien style is really tough and dense, even for an experienced reader.
Science FictionThe Hunger Games, by Susanne Collins. I know this is a modern series, specially for teens and young adults, but the style is so engaging and addictive, that it's worth for someone who starts in the world of literature. The story may have some stupid details, book 3 isn't so awesome, and it's on a kind of post-world-war world, but the story is really interesting and easy to understand, so take it as an entry level book. The great classics are like the prog of literature - wonderfully crafted, but difficult to digest.
OthersChoose Your Own Adventure, by lots of different authors. One of my favorite series ever, and definitely the best books for somebody who is starting to read seriously. These are written in second-person, thus it means that you are the protagonist of the book, and the writer guides you through the story. And the best thing: decisions. You reach a point when you have to decide either one thing or another, and the story can change a lot, specially 'cause of the first choices at the beginning. So, you have different endings, and that depends on the edition, but my favorites are the ones with 20 or more finals, specially those where I die

I think you'll find all of these at your local library, so I wish you good luck on your reading
